Unsuspecting shoppers got a big surprise while enjoying their lunch. Over 100 singers took part in this awesome Christmas improv.

bobregl: Every other performance of Händel's Messiah I have heard had no solos - i.e. full chorus throughout. This rendition starts out with two solos then adds choir voices gradually, building to full throated ending. A stroke of musical genius by the choir's musical director. Bravo for an inspired performance. Händel would be pleased.
